To all whom it may concern.'

Be it known that I, JOHN C. TALIAFnRRo, a citizen of the United States, residingl at Baltimore city, State of Maryland, have invented certain new and useul'Im rovements in Exhaust-Boxes for Canning achinery, of 4which the following is a description `'reference being' had to the accompanylngrawing and'to the` iiguresof reference markedl ingy by a rotating' drum, which drum also serves' as a; medium for supplying steam to the exhaust box A Vfurther object of the ini'ention is to provide an exhaust box of the above charactor with means whereby two rows ofcans may be simultaneously fed throu h the casing by the same Yrotating; drinn, t us greatly reducing the speed of the cans without re ducing the number of cans treated in a given period o f time.

These and other objects will in part bev obvious and will in part be hereinaftenmore fully disclosed.

In the drawings, which show by way of illustration ongegembodiment of the invention:-"

Figure 1 is n view in longitudinal seeltionV through an exhaust box having my improvements applied thereto;

Fig.4 2 is an enlarged sectional view of a vportion of the rotating drum;

Fig-3 is a view. partly in plan and partly in section, of the same;`

Fig. 4 is a vertical sectional view through the machine.

In carrying out the invention, I have provided an exhaust box which consists of a supporting frame on which 1s mounted an elongatedcasng, open in part at each end so as to permit the cans to pass 1n at. one end of the casing, then through the casing, and out at the other end thereof. Extending longitudinally in the ca sing 1s a rotating drum having a proJecting thread sp1- rally wound thereon, which threadi engages the cans and gradually forces the sume through the exhaust box. This drum is per forated and is supplied with steam, prefer-f ably through a central pipe which extends -from end to end of the drum. The-casing go forming the exhaust box' is divided centrally above the drum so that two rows of cans may be simultaneously fed through the exhaust boxand by the same rotatie `drinn. The inner walls of the exhaust the drum in supporting the cans as they are fed through vthe exhaustlbox.

Referring more in detail to the drawings,

my improved exhaust box consists of a sup- 7o portingl frame l, on which is mounted a casing 2. This. casing 2, as clearly `shown in F ig. 4, is'forined with sido walls 3-3 and top and bottom walls 4"-4. The casing is preferably rectangular in crosssection and is elongated so that the cans may be fed through the casing', entering at one end and leavii'iget the other, and While passing through the casing they be subjected to steam. .The casing ispartly open at cach n end.

a rotating drum 5. This rotating drum is hollow and is closed at its ends by heads '6--6- which are formed with projecting g5 drum is a pipe 8. This pipe may also act as a tie-rod for the 'journals ofthe rotating drum. Said pipe is plugged at 91:0 close one .end thereof. while the other end of the pipe is connected to a steam'supply 10. This pipe 8 is formed with a series of perfora- 95 tions 11.

The drum 5 is also provided with a series of perforations 12, an is further provided with a projecting thread 13 which extends spirallv about the drum from end to end :nu

thereof. The casingr 2 is formed with supporting brackets 14 and 15, and with a een.y trai guiding rail 16. This guiding rail is mounted on vhaingrers l? attached to the up per wall of theexhaust box. There is also a side guide rail 16 which is attached to the side wall of.' the casingr E3.A As. clearly shown in Fig. 4, the brackets 1t and 15 er,

x are e5 formed with supporting ledges which assist Extending longitudinally of the casing 4is dividing trigger is supported -receiving end of the box or, 1

tend onl a short distance toward the ccnterof the casing and the thread on the drum proects through, the space between these brac ets.

Tho cans are delivered to .the exhaust nox on a rotating disk 18 which may be driven by a suitable spiral gear 19 on the extended sleeve of the rotating drum. The spiral gear wheel 19 meshes with a cooperating gear on the hub of the disk 18. The cans are delivered onto the disk 18 in any suitable way, and as .the disk rotates the cans are brought against the guide 20.

At the entranceof the casing 2 there is a pivoted dividing trigger 21. This pivoted by the casing above the disk 18 and is formed with an enlarged rear end.` This trigger operates automatically to direct first a can on the left of the central guide 16 in the exhaust box, and then' on the right of said central 'de As a can engages the rear end of the trigger, it will shift the same so that the next can will pass on the other side of theV ide as above noted. In other words, t e cans through the operation of this trigger are automatically and equally distributed on op osite sides of the central guide rail 16.

he cans rest in part on the bracket and in part on the drum and as the drum rotates the spiral thread thereon will force the cans along the exhaust box and linall deliver the same from the o posite en thereof. The drum, as viewed rom the receiving end of the exhaust box, rotates m a counterclockwise direction, as indicated b'y the arrowv in Fig. 4. This rotation of thejdrum tends to hold the cans against the res ectve ide rails 16 and 16.

is abo e noted, there is a steam pipe passing centrally through the drum and, therefore, the drum will be supplied with steam, and inasmuch as the drum is perforated jets of steam will issue from the drumjin and about the cans being conveyed through the exhaust box. These perforations 'in the drum may be formed of such size and distributed so as to meet the re- 4quired conditions. If desired, the perforaf tions at the receiving end of the exhaust box may be greater in number so that a greater amount of steam is su plied at the desired, the n er of erforations may be eater at tlildrlgtber erd of the exhaustvboxgir After the cans are passed through the exhaust box they are delivered onto receiving disks which, as herein shown, are two in number., The disk 22 is a rotating disk and coperates with a closing machine so that the cans will be delivered directly to the closing machine from this disk. A suitable guide 23 maybe provided for directing the cansinto the closin machine. The disk ing longitudinall aving a spira livers the cans onto a disk 25 from which they are delivered to a closing machine. Guide rails 26 and 27 are provided for directing the movement of the cans The receiving disk 18 is preferably located so as tofreceive the filled cans from a illing machine, and from this disk the cans are passed in a double line through the exhaust box. By directing the cans in a double line through the exhaust box they may be carried through the same at a slower speed without reducing the number of cans treated in the exhaust box in a given time. This slower speed not only gives the cans a greater period of time in theexhaust box, but also greatly facilitates the handling of the cans without spilling the contents thereof.

It will be understood that I do not limit myself` in this application to the particular use of the exhaust box shown, as the invention consists broadly in the construction of the exhaust box and the disposition of the rotating drum therein whereby the cans may be conveyed through the exhaust box by the rotatiii drum and steam supplied to the exhaustox through said drum. It is also obvious that minor changes in the details of construction and the arrangement of parts may be made without departing from the vspirit of the invention as set forth in the appended claims.
